Luke Shaw must wait for his Manchester United debut; a hamstring injury has ruled him out for up to a month.

Jonny Evans missed the friendly over Valencia and is doubtful while Antonio Valencia and Michael Carrick are missing.

Meanwhile, Swansea welcome back Nathan Dyer and Wayne Routledge.

Both wingers missed the Swans' final pre-season game at home to Villarreal last week – Routledge had a foot injury while Dyer was attending the birth of his son.

But Swansea manager Garry Monk is without knee-injury victims Leon Britton, Marvin Emnes and Jay Fulton for the trip to Old Trafford.

Match Notes Twelve months after David Moyes started his Manchester United reign with a 4-1 win over Swansea, his replacement, Louis van Gaal, begins his spell in charge at Old Trafford against the same opposition.

There are defensive injury concerns and a shortage of new faces but there is also new system, 3-4-1-2, and Wayne Rooney, so disaffected in Wales a year ago, has been given the captaincy.

Swansea manager Garry Monk has strengthened well and is now confident of keeping striker Wilfried Bony.

Stat of the game: United last loss on the opening day of the season at Old Trafford against Ipswich, 42 years ago. And Bony found the net twice in three league and cup games against United last season.
